•  Evaporative gas between the purge solenoid valve and the charcoal canister is liquefied while being transferred to the extension manifold (upper) due to a decrease in temperature and other factors. The catch tank holds such liquefied evaporative gas (gasoline).
•  Liquefied evaporative gas is held in the catch tank and not supplied to the extension manifold (upper). This prevents an overly rich air-fuel ratio.
